我正在尝试建立一个使用 Elasticsearch 和 Shield 的运行服务。但是，当我尝试启动服务时，出现以下错误：

org.springframework.beans.factory.BeanCreationException: 
Could not autowire field: private java.util.List com.company.AppConfig.identConfigs; 
nested exception is org.springframework.beans.factory.BeanCreationException: 
Error creating bean with name 'demoident' defined in URL [file:C:/path/to/config/foo.xml]: 
Cannot resolve reference to bean 'bar_client' while setting bean property 'searchClients' 
with key [TypedStringValue: value [default], target type [null]]; 
nested exception is org.springframework.beans.factory.BeanCreationException:

nested exception is org.springframework.beans.BeanInstantiationException:

Constructor threw exception; nested exception is 
org.elasticsearch.common.inject.CreationException: Guice creation errors:

4) A binding to org.elasticsearch.shield.ssl.ServerSSLService was already configured

4 errors
    at org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor$AutowiredFieldElement.inject(AutowiredAnnotationBeanPostProcessor.java:561)
    at org.springframework.beans.factory.annotation.InjectionMetadata.inject(InjectionMetadata.java:88)
    at org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor.postProcessPropertyValues(AutowiredAnnotationBeanPostProcessor.java:331)

（抱歉，stacktrace 的格式很难看，请随时编辑以提高可读性）

如果我删除了 Elasticsearch Shield 的 Maven 依赖项，那么服务将按预期启动，没有堆栈跟踪，但由于排除了 Shield，显然无法执行任何查询。

任何帮助或输入将不胜感激。

编辑：我意识到错误是由 Java 客户端引发的，而不是 Elastic 本身。
